We inspect the unit, assess the reported symptoms and advise on the repair required. Work may include replacement of faulty components and reprogramming where appropriate. Genuine parts are used where required for the agreed repair.

The unit is bench-tested after repair to assess operation and stability. If the issue cannot be reproduced on the bench, further in-vehicle checks may be needed.

This service is for confirmed Porsche PCM3.1 audio/navigation units. Please send the vehicle model, build year, VIN, unit part number where available, and clear photographs of the screen, controls and software version.

Cayenne and Panamera owners, as well as owners of other Porsche models, can contact us for an assessment. Vehicle name and year alone do not establish PCM3.1 fitment. For a 911, Boxster or Cayman, confirm the installed system before booking.

PCM3.0, PCM4 and CDR systems require separate identification. The map-card slot shown below is a useful visual reference; the part number and software information should also be checked.

• When the problem occurs: immediately at startup, after warming up or intermittently.
• Whether the display, audio, touch controls and physical buttons stop together.
• Any recent battery event, software work, water exposure or previous repair.
• Any aftermarket interface or accessories connected to the PCM.

A short video of the restart or frozen screen can help us understand an intermittent fault.

Contact Naviplus to arrange an appointment. Tell us whether you are bringing the vehicle or an already-removed unit so removal, refitting and vehicle testing can be discussed and included in the quote where needed.

Turnaround depends on diagnosis, parts availability and the fault. An estimated completion time is provided once the work has been assessed.

1. Arrange the booking: contact us with the unit details and symptoms before shipping.

A warranty is provided on the completed repair. Ask for the applicable duration, coverage and claim procedure in your written quote; a specific warranty period is not stated in this listing.

This repair service does not include CarPlay / Android Auto upgrades, map updates or a replacement headunit unless separately quoted. Repair outcome and cost depend on the diagnosed fault.
